Project Overview

Paraná's SEAB/DERAL publishes daily price quotes for a long list of agricultural products across the state's regions. Until this dashboard, anyone tracking historical movements had to compile the daily releases by hand. The dashboard ingests each release on publication, builds the historical series, and exposes seasonality and regional spread.

Refresh is fully automated via GitHub Actions; the dashboard is open-source and updated daily without manual intervention.

Development Stages

  • Web scraping and ETL from DERAL daily publications
  • Seasonality and regional spread analysis
  • Interactive time series with filters and product comparison

Tech Stack

React DERAL D3.js Time Series Python GitHub Actions

Outcome

Daily agricultural price tracking with automatic updates — the historical series available without manual compilation.
